15 صفحه اولFinite size effects in patterned magnetic permalloy films
Electron beam lithography has been used to prepare 250-Å-thick square-shaped permalloy dots whose width and separation are in the range between 1 and 4 mm. The static and dynamic magnetic properties of these structures have been investigated by complementary techniques such as magneto-optic Kerr effect ~MOKE!, magnetic force microscopy ~MFM!, and Brillouin light scattering ~BLS!. Longitudinal M...
متن کاملControlled magnetic reversal in Permalloy films patterned into artificial quasicrystals.
We have patterned novel Permalloy thin films with quasicrystalline Penrose P2 tilings and measured their dc magnetization and ferromagnetic resonance absorption. Reproducible anomalies in the hysteretic, low-field data signal a series of abrupt transitions between ordered magnetization textures, culminating in a smooth evolution into a saturated state. Micromagnetic simulations compare well to ...
متن کاملLaser-induced magnetization dynamics of lanthanide-doped permalloy thin films.
We investigate the effect of Ho, Dy, Tb, and Gd impurities on the femtosecond laser-induced magnetization dynamics of thin Permalloy films using the time-resolved magneto-optical Kerr effect. Varying the amount of Ho, Dy, Tb content from 0% to 8%, we observe a gradual change of the characteristic demagnetization time constant from approximately 60 to approximately 150 fs. In contrast, Gd concen...
متن کاملFlow of thin films on patterned surfaces
We present fully nonlinear time-dependent simulations of the gravity driven flow of thin wetting liquid films. The computations of the flow down a homogeneous substrate show that the contact line where liquid, solid, and gas phase meet becomes unstable and develops patterns. These computations are extended to inhomogeneous surfaces, and show that inhomogeneity can induce instability of the flui...
